 In [51102] support for adding inline styles for all blocks was added, but
 this makes WP register styles to non-existing stylesheets.

 Steps to replicate:
 1. Add `add_filter( 'should_load_separate_core_block_assets',
 '__return_true' );`
 2. Insert a block that dosn't have a block css. Ex. core/column.
 3. Visit the page and check the network tab to confirm that WP tries to
 load `/wp-includes/blocks/column/style.css` with status 404.

 In Gutenberg this was fixed by adding `false` url to blocks that dosn't
 have a stylesheet. See https://github.com/WordPress/gutenberg/pull/32275
